When Texans offensive lineman David Quessenberry lined up as an extra blocker with the offense against the Pittsburgh Steelers, it completed an emotional, successful victory over cancer.

Quessenberry made his inspirational NFL regular-season debut Monday following a three-year battle with non-Hodgkin T-lymphoblastic lymphoma.

Quessenberry got choked up at his locker while discussing a day he's awaited for years after a medical ordeal that included losing and regaining 70 pounds after undergoing chemotherapy at M.D. Anderson.

"It was everything I dreamed of while I was going through my treatments," Quessenberry said. "Playing a full-speed game was exactly how I'd hoped it went. I would say it was very emotional for me and the people around me and for my family watching. It was just something special."

For his first game since being promoted to the active roster from the practice squad, Quessenberry was named a game captain for the coin toss.
